Setting up a router with the connection from another router

Hello, I'm new to the forumz. I need a little help. I'm in the process of setting up my Linksys(yeah I know) router and my friend has told me not to use the setup cd, ut rather come here to ask for help. I have two computers: one that is connected to the modem and sends the connection through one router to my second computer. I want to be able to take that connection and use a router in order to allow my computer and game system to both be able to be connected to the internet. I need some help setting it up, though. Any suggestions would be greatly appreciated!

There may not be enough ports open on the first router, or he may only have one cable long enough to go from the first router to the second.

I had a problem like this too, but I forget the solution. There was some simple way to solve it, disabling some option in the router's configuration and plugging the cable from the first router into a non-uplink port on the second. I'll look into it.

Thank you everyone for your help! Blue68F100, I will try this method and see what results from it!
